Specification forming part of Letters Patent No. 137,182, dated March25, 1873.

To all whom it may concern:

Be it known that I, TEoMAs E. GROPPER, of Suffolk, in the county ofNansemond and State of Virginia, have invented certain new and usefulImprovements in Measuring-Funnel; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawing and to the letters of referencemarked thereon making a part of this specification.

The nature of my invention consists in the construction and arrangementof a measuringfunnel, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure l is a perspective view of mymeasuring funnel 5 and Fig. 2 is anenlarged sectional view of the joint or connection between the valve-rodand the lever operating the same.

A represents an ordinary funnel provided with a handle, B, as usual, onone side. On the inside of the funnel A is attached a plate, C, whichstands perpendicularly in the funnel, and extends from the side wherethe handle is located to or nearly to the center of the funnel. Theupper edge of this plate also extends a suitable distance above theupper edge of the funnel, as shown. On the inner edge of the plate G areformed guides or loops c a for the passage of the rod b, to the lowerend of which the valve D is attached. The upper end of the valve-rod bis forked, as shown in Fig. 2, and embraces the inner slotted end of alever, E,a pin, d, passing through the prongs of said fork and throughthe slot in the lever, and thus forms the joint or connection betweenthem. The lever E is pivoted between two ears, e e, projecting upwardfrom the upper edge of the plate C, and between said ears and the innerend of the lever a spring, f, connects the same with the edge of theplate. The entire spring f is located above the upper edge of the funneland hence it cannot become clogged up with molasses, te., which is oftenthe case where the spring is located within the funnel below the topedge, and which prevents the valve from closing properly. rPhe outer endof the leverE is flattened, as shown, or otherwise shaped so as to forma convenient thumb-piece, which, when pressed down to raise the valve D,catches on a spring-hook, G, attached to the outside of the funnel, andprojecting through a slot in the handle, thus holding the valve open.The spring-hook G is readily released from the lever, and then thespring f throws the valve D down again, closing the outlet of thefunnel.

The front side of the plate C is graduated to show different quantities,the graduating-marks c i extending entirely across the plate, so thatthe operator can readily see whether the funnel is in proper positionfor measuring or not.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The plate C, extending from one side of the funnel inward to thecenter, and provided with graduating-marks extending across its face,substantiallyv as shown and described, and for the purposes set forth.

2. The combination, with a funnel, of a graduated plate, C, valve D, rodb, lever E, spring f, and spring-hook G, all constructed and arrangedsubstantially as and for the purposes herein set forth.

In testimony -that I claim the foregoing I have hereunto set my handthis 5th day of September, 1872.
